16 Claims.

This invention is an improvement in combination metal sash frame and housing therefor for operative mounting in the window opening of a building.

It is designed to provide a completely operative equipment for sliding engagement with the inner surrounding stationary framing and in cooperation with interengaging slide members thereof, balancing suspending means, etc. and is constructed as hereinafter described and shown by the accompanying drawings; in which:

Fig. l is a perspective exploded or disassembled view showing the sash frame, housing elements, and lifting cords spaced therefrom;

Fig. 2 is a vertical sectional view, partly broken away, showing a pair of upper and lower sashes and housings, in closed position;

Fig. 3 is a cross section of one side only on the broken line III--III of Fig. 2;

Fig. 4 is a similar view of one sash and side housing only, illustrating one step of assembling such members;

Fig. 5 is a similar view illustrating the step of firmly connecting the sash frame with the housmg.

In my companion application filed herewith Ser. No. 133,485, I have shown and described my improved window sash in detail, consisting of the usual light 2 confined within a mounting frame :10 between separable front and back members 3 and 3 adapted to make interlocking connection with each other. One of said frame members as 3 is provided entirely around its top, bottom and side edges with a continuous laterally extending dove- 35 tail extension rib 5. The dovetail is cut away at the four several corners as at 6 for clearance of the outer housing members, providing projecting key elements, in application thereof.

The housing members and each housing frame 40 of both upper and lower sashes are substantially the same, except as to the lower and upper meeting rail portions of each respectively, and an additional lifting rib extension at the bottom of the lower member.

The top and bottom portions of the enclosing window opening framing are provided with a weather sealing rib 'l and an inner and outer flanking rib 8, when desired, although the latter is not absolutely necessary.

For interengagement with the side edge portions of both upper and lower sash frame housings, the surrounding aperture framing is provided with vertical ribs 9 extending from any suitable mounting, for guiding and weather strip 55 action, like ribs 1.

Each housing is substantially the same, as stated, in that it consists of a terminal horizontal bar I0, vertical side bars H, II, and an opposite horizontal bar l2, each having dovetail sliding and clinching connection with one of the sev- 5 eral dovetails 5 by dovetail sockets 5a. Side bars H extend only for the full length of side dovetails 5, to their terminals at cut out corners 6, while horizontal bars Hi and 42 extend across their ends and terminate coextensive and flush 10 with the outer edges of bars ll. Excepting'the meeting rail bars l2 only, each of bars I 0 and H is provided with a Ushaped opening I3 and inwardly turned retaining lips I 4 for reception of an inserted U-shaped sliding strip l5 having a 15 middle groove to engaging ribs 1 and 9. Strip i5 is of any suitable sliding, lubricating and packing material as felt or the like, for weather and sound proof functioning.

A further material advantage of the strip i5 is that it prevents metal to metal contact, avoiding abrasion or galling due to friction, with continuous quiet and easy operation.

The ends of bars and i2 are cut out as at IT in register with and forming continuations of 5 the side grooves of bars I I, and of proper width to slidably engage the side ribs 9.

The overlapping ends of bars H) and H are securely connected with the abutting ends of bars H in any suitable manner, as by welding, 30 thus firmly enclosing the sash frame all around. Otherwise, the fixed attachment to the sash frame is sufiiclent.

Each sash frame housing is provided on one of its sides, preferably front and back, with a pair of oppositely located sash cord sockets i8. These as shown are conveniently formed of sheet metal blanks shaped to provide a partly cylindrical bifurcated shell and a securing extension l9, held to the face of each side bar 6 i, as byscrews.

The sash cord 26 provided with a terminal abutment 2! is inserted through the clearance opening 22 with the abutment engaging the lower edges of the socket wings, and these may then be pressed inwardly to prevent disengagement. a companion application filed herewith, Ser. No. 133,487, I show related construction of the embracing window opening framing in which the sash weights, pulleys, etc. used with the cords 20 are disclosed in their operative relationship.

Each meeting rail bar I2 is shown as continuously flat and extended towards its companion housing and provided with a wedge shaped flange or rib 23 for sealing engagement with a similar one of the companion housing, as in Fig. 2. A 55 sealing strip 24 of suitable material as felt or rubher, is inserted in a receiving socket 25 extending for the full length of each bar along its inner face.

Such socket is undercut at each opposite edge for secure holding of the strip 24, as shown. Each bar I2 is also shown as having an extension 26 projecting beyond its sealing flange 23 and practically closing" thespace between the pair vof flanges and the opposite housing when the flanges are in engagement.

By means thereof I thus substantially prevent entrance of foreign matter, dust, rain, snow, or air currents around these junction elements when the windows are closed, or when the flanges are.

. ciently malleable material, as aluminum.

In assembling the several housing members around the sash frame in the manner described it is desirable that they be permanently secured together after being slidably joined-by the interengaging dovetails 5 and the receiving sockets therefor 5a. These as shown are provided be tween opposite embracing extensions 28 of bars in, II and I2, each having female inclined faces generally conforming to those of the dovetail 5.

For the purpose of freely fitting slide engagement sufficient clearance is provided by proper extrusion die design, and one of the extensions 28 extends slightly beyond its final desired registering plane with the edge of the sash frame member, as at 29. In securing the two members together in final fixedly connected form, the opposite extensions 28 are subjected to inward pressure, as by action of a pressing roller 30 at one side and a resisting anvil surface 3| at the other; see Fig. 5. In such compression the dovetail is firmly secured and embraced, particularly at the acute angle groove junctions between the parts.
